Description A 1.650 g sample of containing lithium hydrogen carbonate is decomposed with heat into lithium carbonate and carbonic acid what is the actual yield of lithium carbonate if this reaction proceeded with 95% efficiency?
Description Consider the following reaction: 4NH3(g) + 5O2(aq) --> 4NO(aq) + 6H2O(g) a) if the container were to have 10 molecules of O2 and 10 molecules of NH3 initially, how many total NO and H2O molecules will form? Please show your work, or explain your answer. b) what is the limiting reactant? Explain. c) How many, if any NH3 molecules remain when the reaction is complete? Show your work.
Description Neurons throughout the nervous system evoke specific outcomes (cellular or whole animal behaviors). Not every neuron evokes the same outcome. What are the factors that allow specificity in the nervous system? Explain how two different responses may be evoked by the same neurotransmitter. Give a specific example.
Description Calculate the Critical Micelle Concentration (CMC) for the phospholipid DPPC, which has two C16 chains attached to a phosphatidylcholine head-group. The energy required to transfer a lipid molecule from the bilayer to water is around 75 kJ mol-1. Estimate how much larger the CMC would be if one of the chains was removed. Question is from Ch.9 and Ch. 10 of this book. http://www.fulviofrisone.com/attachments/article/403/soft_condensed_matter_jones_oup_2002.pdf
Description The human body obtains 1035 kJ of energy from a candy bar. If this energy were used to vaporize water at 100.0 ?C, how much water (in liters) could be vaporized? (Assume the density of water is 1.00 g/mL.) Please explain how you got your answer!
